First, I would try deleting the application preferences located in ~/Library/Preferences/com.earlyinnovations.PhotoLinkerIf that works, try opening the Geotagging Console (because that's what it's crashing on).

Second, I would try downloading a new copy of PhotoLinker. It's having trouble with one of the built-in resources, so it's not unreasonable to think that a fresh copy won't make a difference.

Since loading the nib seems to be the problem, maybe it's related to language settings. Could you try making English the primary language, if it's not already, and see if that makes a difference? Actually -- maybe also try making the "Formats" set to "Region: United States" as well (these are all under the Language & Text settings). We had a crash a while back related to formatting, so if you're defaulting to something else I wouldn't be surprised if that's causing the crash.

Ok - I tried to reproduce the same behavior on another machine. On my older MacBook Pro, Adobe Acrobat prompted that I update to v8.3.0 - update went smooth. And PhotoLinker application opened just fine after this update, confirming your findings (that timing of Adobe Update had nothing to do with the behavior of PhotoLinker on my newer MacBook Pro).

I rebooted the old MacBook Pro just for kicks and PhotoLinker still opens just fine.

Wondering if this problem was just isolated to my account on this machine, I created a new account (standard user, no admin powers) on my new MacBook Pro - except for an initial warning (that 'filename is invalid') every time I try opening it, PhotoLinker does open successfully - lets me add tracks and tag photos as well.

So, it does look like problem is somewhere just within my account (which has admin powers). Any thoughts/help please?
